89C51电子血压计毕业设计论文 ABSRACT The rapid development of modern society, leading to deteriorating environment, unhealthy living habits and unscientific eating habits, leading to the emergence of an increasing number of human diseases. Which has one invisible killers of the human hypertension, and has gradually risen to the top ranks of human disease, a long-term hazard to human health, so that patients suffering from hypertension pain. How convenient and effective measurement and monitoring hypertension, and thus effective prevention and treatment of hypertension, a confrontation hypertension is the most important issue. Therefore, design a convenient measurement of blood pressure devices, has become a priority. This article will detail the design of our intelligent blood pressure measuring devices. Home Blood Pressure Monitor, mainly for home. Home health care has become a fashionable modern health care. Measuring blood pressure in the past people have to go to the hospital for the job now as long as the electronic blood pressure monitor has a home, sit at home monitoring of blood pressure can be at any time, such as abnormal blood pressure can be found in time to the hospital for treatment, prevention plays a cerebral hemorrhage, heart failure The role of diseases such as burst.
